ABSTRACT

‘PROBING EQUIPMENT PLATFORM, FITTED WITH A MOBILE LIFTING AND LOWERING MECHANISM FOR TRANSPORTATION AND LIFTING AND LOWERING SYSTEM OVER THE DRILL SHAFT HEAD’ For lifting and lowering the probing platform. The mechanism has a base ( 9 ) with brackets ( 12 ) and arms ( 5 ) running in the pantographic system, connected under the platform ( 1 ) floor ( 1 ). By the brackets ( 12 ) movement, the assembled and compacted platform (I) in a warehouse may be lifted and lowered automatically to the set over the body (C) of a dolly and taken to the surface of the drill shaft head, as it is taken off and lifted automatically as well by the pantographic system of the arms ( 5 ) and positioned for the probing procedure. As soon as the probing is concluded, the platform ( 1 ) is lowered by the arms ( 5 ) and set once again automatically in the dolly body (C) by the brackets ( 12 ), as it may be brought back to the warehouse or taken to other drill shafts, and so forth for new probing procedures.

The descriptive report hereof is a patent of invention request for amechanism developed to automatically provide full mobility to theprobing equipment platform, enabling it to be lifted and lowered, as itis assembled to lay it down to a dolly structure, thus taken with thedrill shaft head, where it is easily lifted and lowered, likewise withits entire structure assembled. For the proposed system, the platformmay be taken to consecutive drill shafts for probing procedures and itcan be then positioned and retrieved (already assembled).

TECHNICAL STATUS

As it is known by probing system technicians and professionals, aftermaking the drill shaft head, a platform is set over it, from which thecolumn and drilling equipment are input.

Aligned to the portion prepared previously in the ground (shaft head),the drill probe has a telescopic column whose structure is positionedvertically, forming a curb from which the drilling column tooling (ringgear, water tank, tubes and other elements) shall be input to carry outthe probing. As said, the column for the drilling column has atelescopic system so all its components may be retracted due tohydraulic power, and then be compacted and laid down over the platformflooring.

The platform generally must have its structure assembled over the drillshaft head, and, naturally, the transportation of the ground, ladder andhandrails and its whole structure is placed in trucks until it reachesthe probing place. It requires an expertise metal structure assemblyservice, valuable time and concerns regarding the arrival of suchelements. It also occurs with the disassembly after the probing isfinished, requiring assembly professionals to be hired, resulting insuch steps, high operational and financial expenses.

PATENT OBJECTIVE

The mechanism hereof and the system related to it (purpose of the patentof invention request) intends to simply eliminate platform assembly anddisassembly steps, that consequently may be stored or transported withits entire structured assembled (including the main probing with thecompacted telescopic column laid down over its flooring). Then, theplatform may be automatically lifted and lowered afterwards to be putover the dolly body and carried through the drill shaft head, as it isalso retrieved and lifted automatically there, and positioned for theprobing procedure. As soon as the probing is concluded, the platform islowered and set once again automatically in the dolly body, as it may bebrought hack to the storage warehouse or taken to other drill shafts,and so forth for new probing procedures.

Thus, the mechanism hereof has a receptor base in its vertices withmovement brackets (horizontally and vertically). Besides, the mechanismbase has attaching rails of the arm lower edges interlocked, linkedthrough the center axle, as the arm upper edges are attached to therails fitted under the platform flooring. The lower edges of the armsare attached to the plunger of a hydraulic piston on the mechanism base.By hydraulic power, such arms may be opened or closed, pulled or pushedby sliding through the rails in the pantographic system. While open, thearms force the platform to lift, and when they are closed, they force itto lower.

Thus composed (assembled and jointed with the compact telescopic columnset over the flooring), the platform is stored in a warehouse ortransported as it is lowered, i.e. with the mechanism arms open. For itstransportation, the base brackets are horizontally extended in order toexceed the dolly body width, then activating the entire platformvertically by lifting it from the ground, intending to exceed the bodyheight so the latter may be placed under the mechanism base. Then suchbrackets are retracted, resulting in the platform lowering reversemovement, also from the ground, making it set on the dolly body,retracting it horizontally.

In such condition, the platform may be transported in analready-assembled position, in roads, to the drill shaft. At the place,after taking the body off by activating the brackets in a reversemotion, the platform is properly locked by the mechanism base on theconcrete ground together with the drill shaft head, then lifted andpositioned by the arms in a pantographic system. Then, after positioningthe telescopic column vertically the probing equipment may receive thedrilling column to perform the probing procedure.

After finishing the probing the telescopic column is retracted and laiddown over the platform, as the arms are moved again to lower it in apantographic system. Afterwards, the brackets are activated so the dollybody is set, and the assembled platform may be transported to be storedor directly to other shaft, and so forth.

In an overview, the mechanism and systems related to it may be explainedin a more detailed way by the drawings attached, whereby they are:

Picture 1—perspective view of the platform fitted with such mechanism,positioned in the lifting condition together with the drill shaft head,as its telescopic column is structured for the probing procedure. Aschecked, the brackets are located in the mechanism base, in addition tothe rails attached to the arms lower edges, connected to an hydraulicpiston plunger, The arms are interlocked and connected between them by acenter axle, as the upper edges are connected to rails under theplatform flooring.

In the pictures shown below, from 2 to 6, it presents the lifting andlowering system to set the platform on the body, to transport it to theprobing place;

Picture 2—side view of the platform stored in a warehouse, in loweredcondition, i.e., mechanism arms open, after sliding the rails byhydraulic power pressing, In this condition the laid-down platform withthe telescopic column is lowered by its arms to its base;

Picture 3—upper view of the platform that shows the aligned body of adolly, Brackets are extended horizontally, as shown in the sides, whichexceed the body (wheel house) length;

Picture 4—sequentially show the sides of vertically-activated brackets,forcing them from the ground to lift the platform until it exceeds thedolly height. In this condition the doily may go backwards and put itsbody under the mechanism base;

Picture 5—sequentially shows at its sides that after inputting the body,the vertically-activated brackets are retracted until the platform islowered and set by the mechanism base;

By the picture below (7), the platform lifting and lowering systemdiagram is presented along with the drill shaft head:

Picture 7—sequentially shown in the sides that after reaching the drillshaft head and the reverse movement activation of the brackets toretrieve the body and lower the platform in order to set it in theconcrete floor around such shaft head, the pantographic system isactivated by the mechanism arms. As observed, as long as the arms arepulled by the hydraulic piston plunger, sliding through the rails, it isdosed and it lifts the platform by the pantographic system, positioningit over the shaft head, proceeding with the vertical positioning of thetelescopic column to the drilling column.

According to the attached drawings, the ‘PROBING EQUIPMENT PLATFORM,FITTED WITH A MOBILE LIFTING AND LOWERING MECHANISM FOR TRANSPORTATIONAND LIFTING AND LOWERING SYSTEM OVER THE DRILL SHAFT HEAD’, object ofthe patent of invention request hereof, is its comprised of a platform(1) used over the oil/gas shaft head, supporting the probing equipment,in such flooring (2), and receptor rails (3) of the upper edges (4)attachments from a set of arms (5) interlocked and fixed between themthrough a horizontal axle (6) are installed.

The arms (5) have their lower edges (7) attached to parallel rails (8)to the rails (3) installed over a receptor base (9) of the hydraulicpiston (10), whose plunger (11) is connected to the lower edges (7) ofsuch arms (5). This base (9) receives such bracket (12) in its verticeswith hydraulic pistons activated horizontally and vertically, formingthe mechanism adapted to the probing equipment (1), as it isspecifically shown in picture

As the equipment is comprised of such items, it shall have thetelescopic column (T) retracted and laid down by hydraulic power overits chassis (2), thus it can be compacted and stabilized when the arms(5) are open with its upper (4) and lower (7) edges, at apposite sides,pressed by the plunger (11) of the piston (10), as shown in picture 2.In this condition the platform (1) may be stored assembled in awarehouse, for example, of the probing company or may be transported,

For use in the probing procedures, as shown in picture 3, the platform(1) along with the probing equipment above, receives the body (C)alignment from a dolly, then the brackets (12) are extended horizontallyby their hydraulic pistons. After exceeding the body (C) wheel housewidth, the brackets (12) arc vertically activated, as shown in picture 4sequence, forcing the platform (1) to lift itself from the ground (8)until the mechanism hose (9) exceeds the body (C) height. After handlingthe dolly and inserting the body (C) under the base (9), the pistonsrelieve their pressure and the brackets (12) are gradually retracted,lowering. the platform base until it touches the body, now moving awayfrom the ground (S) proportionally in the opposite direction of theweight applied by the platform (1), which lowers itself to the mechanismbase (9), setting it smoothly in the body (C) as shown in picture 5sequence, Then the pistons activate the brackets horizontally towardstheir retraction, along with the body (C) sides, as shown in picture 6.

After being set, the assembled platform (1) may be transported on roadsto the probing place, where the dolly is parked with its body (C) overthe concrete floor (P) around the drill shaft head, as shown inpicture 1. After activating the brackets (12) in a reverse direction,the platform (1) left by the dolly is lowered and locked in the concretefloor over the drill shaft head.

Afterwards, the piston (10) is activated and its plunger (11) pushes thelower edges (7) of the arms (5) that, along with their upper (4) ones,slide through rails (3) and (8), closing itself against its horizontalaxle (5), in the pantographic system. As shown in picture 7, as long asthe arms (5) are pushed and closed by the hydraulic power, thepantographic lifts the platform (1) from the base (9) until the formeris properly positioned over the drill shaft head. At last, thetelescopic column (T) is positioned vertically to receive the drillingcolumn to perform the probing procedure.

After concluding the drilling the telescopic column (T) retractionoccurs, laid down over the platform (1) floor (2), then when the piston(10) is once again released to open the arms (5) by the pantographicsystem, in order to lower the platform (1) and bring it against the base(9). Thus the equipment is ready to be transported by dolly to otherprobing place or taken to the warehouse to be used again, as the samesystem is still required.
